Next up on "The heat index," the new app designed to create more quality time with your kids. With a click, parents with grab their children's attention by turning off their phone. Becky Worley has the story. Dinner time is happy time for this family. They talk about the good things that happened each day. Reporter: Family dinners have changed. Everybody, gadgets down, now. Why are you freaking out? Because you're all so involved with your little gizmos, no one is even talking. Reporter: Technology has wormed in to every aspect of family life. Will you set the table outside? Reporter: Beat the Ellie and Cameron. And a slew of personal devices that cause problems. Phones get 80% of the attention and you're getting 20%. Let's do the homework. Let's clean the table. Let's do what there is to do around the house. And their face is in the phone. Reporter: A new, free app is hoping to solve problems like these. It's called dinner time. Install it on the devices. And the parents have control. They need a timeout from technology? Like to take a break? And again, the phone is locked. For more parents, the real issue is -- when do you look at your phone most? Probably before I go to bed. Reporter: Tell the app to block the phone from 9:00 P.M. To 7:00 A.M. And the parents don't have to physically confiscate the device. That's the real power of the app. You think it would cause less conflict if your parents could just shut your phone off from theirs? Yes. Reporter: Why? Not as much arguing. Reporter: There are limitations, for this app, the parents can have iPhone. But the kids have to have android devices. How brilliant is that idea? The kids pretending they're okay with it. That's fine with us. Less arguing. A way to circumvent. We want to know how you get your kids off their digital devices. I yell. Tweet us @"Gma," #social square. Let's go out to central park
